Credit challenges

» Sizeable capital expenditure plan across both the utility and renewable segment carries some execution risk

» Material weakness finding in audited financials point to corporate governance challenges

» Ring-fenced utilities create separateness and insulation from AGR family

Rating outlookAGR’s stable outlook reflects the strength of its regulated utility subsidiaries that account for 65% of operating cash flow generation,the largely contracted nature of its unregulated business, as well as access to incremental liquidity from a deep-pocketed majorityowner. The outlook also takes into account our expectation that its holding company leverage will gradually increase over time andresult in lower credit metrics that are more in line with its rating, such as cash flow from operations pre-working capital to debt (CFOpre-WC/D) in the high teens.

Factors that could lead to an upgrade

» Material improvement in the credit supportiveness of the regulatory frameworks within which AGR’s regulated utilities operate

» Sustained strong financial ratios such that CFO pre-WC/D exceeds 26%, on a sustainable basis

Factors that could lead to a downgrade

» A deterioration in the credit supportiveness of the regulatory jurisdiction across which AGR’s utilities operate

» A weakening in the company’s financial results, such that CFO pre-WC/D falls to the mid-teens and retained cash flow to debtdeclines to the low teens, on a sustained basis.

» An increase in the percentage of consolidated operating cash flows derived from the more volatile, non-contracted unregulatedsegment

» A material weakening in the credit quality of its majority owner, Iberdrola S.A., or increased dividend payments from AGR to itsshareholders.

Detailed credit considerationsREGULATED UTILITIES PROVIDE FUNDAMENTAL CREDIT SUPPORTAGR’s ownership of eight low business risk regulated utilities, operating across four different states in the northeastern U.S., andrepresenting a total rate base of $9.1 billion, provide a strong, predictable, and stable base to the group’s overall operating cash flowgeneration. Together, these utilities represent about 65% of the company’s consolidated cash flow generation, and account for 80% ofconsolidated debt.

Exhibit 4

Source: Company presentation

AGR’s core utility holdings operate in mostly constructive regulatory environments. AGR’s New York and Maine-based transmissionand distribution (T&D) utilities as well as its FERC regulated transmission segment account for 77% of consolidated rate base, andbenefit from the most credit supportive regulatory environment of the consolidated group. Some of the favorable ratemakingmechanisms available in these jurisdictions are the application of a forward looking test year and formulaic equity returns. These allowfor transparent and predictable rate setting and for timely recovery of operating and capital costs.

AGR’s natural gas distribution companies (LDCs) account for 12% of consolidated rate base. They operate across the somewhat morechallenging but improving regulatory jurisdictions of Massachusetts and Connecticut. Although these companies have a history offully litigated rate cases, they have access to decoupling and infrastructure tracker mechanisms. Decoupling is credit positive since itsupports the stability of operating cash flow generation by shielding the companies from the demand volatility associated with weatherand customer demand. Similarly, the infrastructure tracker mechanisms are credit positive since they provide for assured recovery ofprudent reliability infrastructure spending on a timely basis.

From a credit perspective, AGR’s weakest and most challenged utility company is United Illuminating (UI, Baa1 stable), its Connecticutbased T&D company, that accounts for 11% of consolidated rate base (when excluding UI’s FERC regulated segment). Like its sistercompanies, it has access to the state’s decoupling mechanism but does not benefit from the reliability infrastructure rider available toConnecticut LDCs. Furthermore, the company has a history of experiencing more challenging general rate cases than its sister utilities,that, to date have only been resolved through a fully litigated process.

HISTORICALLY STRONG FINANCIAL RATIOS BUOYED BY LOW DEBT LEVELS AT PARENT AND UNREGULATEDSUBSIDIARY WILL WEAKEN OVER TIMEAbout 80% of the company’s consolidated debt is at the company’s regulated utilities, that are levered in accordance with theirregulatory capital structure of between 40%-45%. The remaining 20% of the debt relates to a limited amount of project financedebt at its unregulated subsidiaries as well as $1.05 billion of debt at the parent (up from $600 million a year ago). The relativelylow amount of debt at these entities, as well as the healthy operating cash flow generation from the unregulated segment’s 6.5 GWportfolio of largely contracted wind farms, results in strong debt coverage and debt to capitalization ratios.

Going forward, we anticipate that the company will continue to gradually increase the leverage at its holding company. AGR istargeting a dividend payout ratio of 65-75% at a time when it is stepping up capex across its largest operating utility and unregulatedsubsidiaries, and generating lower operating cash flows due to the passage of federal tax reform.

AGR's operating cash flows are forecasted to fund about 80% of its capital investments, with the balance coming from incrementaldebt at the parent and the utilities, and tax equity at the company's unregulated segment. AGR will also rely on incremental parentdebt issuance to fund its dividend. Although not a sustainable long-term approach, with a CFO pre-WC/D of about 23% and debtto capitalization of around 32%, there is some room for incremental leverage, assuming its business mix remains unchanged and itcontinues to benefit from constructive regulatory relationships across the jurisdictions where it operates.

LARGELY CONTRACTED NATURE OF RENEWABLE ASSETS AND SALE OF NATURAL GAS BUSINESS IMPROVEUNREGULATED SEGMENT’S RISK PROFILEFollowing the sale of its natural gas trading and storage business, AGR’s unregulated business, Avangrid Renewables Holdings, Inc.(Renewables), now solely consists of 7.1 GW of generation capacity, with largely contracted renewable sources accounting for 6.5 GWof the total. Importantly, prior to the sale of its natural gas business, Renewables already accounted for 100% of the segment’s EBITDAand has a record of producing generally stable operating cash flows. About seventy percent of AGR's generation capacity is contractedunder long-term power purchase agreements with an average life of 9 years to credit-worthy offtakers, while 5% to 15% of the balanceis hedged.

In 2017, AGR's management announced its plan to exit the natural gas business as it viewed it as non-core and not aligned with thebroader company's strategic objectives. Furthermore, as a minor cash flow contributor, generating only about 5% of the company'sconsolidated cash flow in 2017, it carried materially more business risk than AGR's other segments. On 1 March 2018, AGR closed atransaction to sell Enstor Energy Services, LLC, AGR’s gas trading business to CCI US Asset holdings LLC near fair market value ($66million subject to working capital, cash and other adjustments). On 1 May 2018, AGR closed a transaction to sell Enstor Gas LLC, its gasstorage business, to Amphora Gas Storage, LLC for $66 million subject to working capital, cash and other adjustments. The transactionprice was lower than the estimated fair market value of the business by approximately $9 million.

MATERIAL WEAKNESS FINDING IN AUDITED STATEMENTS POINTS TO CORPORATE GOVERNANCE CHALLENGESOn 26 March 2018, AGR released its 2017 10-K which included disclosure of a material weakness in an adverse auditor opinion onthe effectiveness of the company's internal control over financial reporting, a significant credit negative. Although AGR's 10-K auditwas unqualified and required no financial statement restatement, the existence of a material weakness for the second consecutiveyear demonstrates an inability of AGR's board and management to effectively implement certain specific, satisfactory internal controlprocesses that are standard practice among industry peers.

The 2017 material weakness relates to internal controls over the measurement and disclosure of income taxes. This is an issue initiallydisclosed in AGR's 2016 10-K and highlighted as one of three material weaknesses at that time. While the other two weaknesseswere addressed over the course of 2017, AGR failed to fully remediate the inadequate internal control processes and proceduressurrounding measurement and disclosure of income taxes prior to their 2017 audit. The company expects to address the issue throughacceleration of the deadline of key activities, increasing its capabilities in the area of income tax accounting resources, and enhancingthe automation of income tax processes and controls to allow for more timely completion of enhanced review of internal controls.AGR currently anticipates that all remediation efforts will be completed by 31 December 2018. See Moody's Issuer Comment entitled“Avangrid discloses existence of a “material weakness” in its 10-K for second year in a row, a credit negative” for more details on thematter.

LINK BETWEEN AGR’S CREDIT AND ISA SOFTENS FOLLOWING ITS LISTING ON THE NYSEThe decision to list AGR on the New York Stock exchange and effectively reduce ISA’s ownership of the company by roughly 20% inDecember 2015, leads Moody’s to conclude that the historically tight linkage between both companies has softened. Although weacknowledge that AGR is an important component of ISA’s overall growth strategy, we believe that AGR is largely run independently.We expect that the company will continue to raise the bulk of its debt through the US capital markets, as well as seek to leverage itslisting on the NYSE to raise equity for opportunistic growth potentially diluting ISA’s ownership further.

Additionally, the presence of ring fencing provisions at all of its utilities limit ISA’s flexibility with regards to its ability to drawdistributions from those entities. Furthermore, AGR’s decision to refinance the legacy UIL Holding company debt at AGR rather than atISA is additional evidence of a de-linking of the two companies. That said, we continue to acknowledge that the majority ownership byISA remains a credit positive, particularly since it provides an additional venue to access liquidity at an advantageous price.

Liquidity analysisAGR’s maintains good access to liquidity. AGR had $40 million of cash on the balance sheet as of 31 March 2018 and maintains a five-year bank credit facility with an aggregate borrowing limit of $2.5 billion (increased from $1.5 billion on 29 June, 2018). The bank creditfacility, that among other things serves to backstop AGR’s $1 billion commercial paper program, has a termination date of June 2023,does not include an ongoing material adverse change clause, and the only financial covenant is a maximum allowed debt to capitalratio of 65% that AGR comfortably satisfied as of 31 March 2018. As part of the recent upsizing and extension of the bank facility,AGR added a sustainability-linked pricing metric that permits an interest rate reduction for meeting targets related to environmentalsustainability and highlights AGR's commitment to enhancing its environmentally friendly business profile.

The consolidated group had $869 million of availability under the then $1.5 billion bank credit facility as of 31 March 2018 after givingeffect to $631 million of commercial paper outstanding. AGR’s utility subsidiaries have various debt maturities totaling $491 millioncoming due in 2018 and 2019. The next AGR level maturity is scheduled for 2020 when $450 million of senior unsecured notes aredue.

AGR employs a centralized approach to managing its liquidity. To the extent possible given certain regulatory restrictions, AGRconcentrate its cash at the holding company and primarily conducts its short-term borrowings through AGR. The utilities optimize theircash balances through a virtual money pool arrangement. Under the terms of this agreement utilities may lend to each other but notto their unregulated affiliates or parent. These terms meet a regulatory requirement set at the time of AGR’s acquisition of the utilitycompanies which prohibits utilities from lending to unregulated affiliates, including AGR.

Aside from modest cash balances, AGR’s principal source of liquidity are its commercial paper program and its bank credit facility underwhich it may borrow up to $2 billion. AGR also recently entered into a $500 million inter-group credit agreement with ISA. The inter-group credit agreement has the same financial covenant as the one listed in the bank facility, and terminates the earlier of 28 June2023 or the date when ISA ceases to own at least 50% of AGR's outstanding common stock. Proceeds from the inter-group creditfacility are used to provide credit support to AGR's CP program and for general corporate purposes.

AGR is also party to a notional cash pooling arrangement along with other ISA subsidiaries. Parties to the agreement may deposit fundswith or borrow from the pool, provided that the net balance of funds deposited or borrowed by all pool participants in the aggregateis not less than zero. This agreement provides AGR yet another avenue for liquidity, supplementing its access to the bank market, anddebt and equity capital markets.

For LTM 31 March 2018, AGR generated $1.9 billion in cash flow from operations, invested $2.3 billion in capital expenditures, andmade $535 million in dividend payments to its shareholders, yielding a $906 million negative free cash flow balance was financed with$585 million of incremental long-term debt and short term debt. Over the next 12 to 18 months, we anticipate that the company willremain free cash flow negative and will finance the shortfall through incremental debt.
